About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X330TC
The SC160X330TC is a double-acting pneumatic cylinder delivering 10053 N of push force at 0.5 MPa (18095 N at the 0.9 MPa maximum operating pressure). Its 40 mm diameter piston rod and 29 mm adjustable air cushion are built to manage heavy linear loads with controlled end-of-stroke deceleration.
This model includes the TC centre trunnion mount, supplied with the TCM1 bracket (part code F-SC160TC), allowing the cylinder to pivot during operation. With a 330 mm stroke and a body length A of 239 mm, the total extended length reaches approximately 569 mm, making it a compact yet powerful actuator for swinging or articulating machinery.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X330TC Is Used
Heavy-Gauge Clamping
Delivers up to 18095 N of clamping force at 0.9 MPa, ideal for holding large weldments or structural assemblies during fabrication.
Pivoting Conveyor Gates
The TC centre trunnion mount lets the cylinder body swing, perfect for actuating diverter gates or sorting paddles on high-capacity material handling lines.
Press & Forming Assist
Provides the sustained push force needed for light press-fit operations, bending fixtures, or die-cushion applications in metal forming.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X330TC the Right Cylinder?
Choose the SC160 when your application needs roughly 10000 N of force at standard plant air pressure. If you can accept a smaller envelope, stepping down to the SC125 bore reduces push force to 6136 N at 0.5 MPa; for higher force demands, the SC200 bore provides 15708 N at the same pressure. The 330 mm stroke on this 40 mm rod is well within standard limits, but always check for side loads—if the load is not guided, consider adding an external linear guide to protect the rod bearing.
For direct replacement, match five points: 160 mm bore, 330 mm stroke, PT port thread, TC centre trunnion mounting (with TCM1 bracket), and the non-magnet version. This tie-rod cylinder is not dimensionally interchangeable with ISO 15552 profiles.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac AIRTAC SC125-160 Standard Cylinder SC160X330TC FAQ
At 0.5 MPa, the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf.
No. The SC160 is a standard double-acting cylinder and will drift or drop if pressure is exhausted. To hold a position without live air pressure, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
